Application filed December 22, 1916. Serial No. 138,355.

To all whom 'it may concern.' f

*Be it known that I., HENRY JANDER, a citizen of the United 'States' ofAmerica, resid,- ing at Brooklyn, "Kings county, and vState oit 'New York, have invented certain ynew andJ useful Improvements in Baking-Ovens, of Which the following is a full, clear, and exact description. l t

'This invention relates to bake ovens l'of the :kind in which the baking chamber receives its heat from iuid heated by the action of combustion, the baking being thereorecaused by transmitted heat. The'said invention-consists in certain improvements in the heating means and other features fofk the oven substantially as hereinafter more particulaily'set forth yand claimed.

" I Will now proceed'to-describemy invention in detail, the novel features of `which I will point outin the appended claims, referencebeinghad to the accompany-ing drawings', forming part I-h'ereof, wherein :f-

'FigQ is a planvietv'thereof; f Y

As herein embodied, fmy invention consists of a baking ovenffcomprisinga lire-box 1 and a chamber 2, Whichconstitutes the oven proper. Thelfrebox andcharnber :are separated by a Wall or `Iy'par-''.ition Sand are in no Way placed in direct communication. The reboX communicates with a Suitable stack d, as can be seen in Fig. l.

Within the rebox l, I locate -a Water tubular boiler, consisting of the mud-drum 6, steam chamber 7 and a plurality .of verf tical tubes 8, one only being illustrated. To the steam drum 7 I Aconnect one end of a manifold or duct 9 havingy depending branches 1() and l1, which in turn are provided With nozzles 12 and `13, respectively (see Figs. 13, 4 and 5), each nozzle Lbeing prov-idedwith a valve 14C. The valve-controlled nozzles12 serveto direct a steam jet onto'the projecting ends of Water receptacles 15 and 16 to blow ashes thereo in order to keep same clean. The valve-controlled noz zlesvl ser-'ve `to introduce steam/into the' compartments 17 of the chamber 2.

To 'form :the compartments 17,1 provide horizontally disposed shelves or partitions 18v made'up of a layer of asbestos .19 between sheet-iron plates y20 and 21 4(see Fig. 29. The shelves or partitions 18vserve to Adivide ithechaniber 2 into the said compart- Furthermore, the V.said compartments 17. ments arev insulated one `from the other `lby the layers 1910i asbestos. Each compartment l?? kcontains a long receptacle or pipe 15 and la vshort @receptacle or pipe 16, the longer one being located at the bottom or" the compartment. Each receptacle 15V is clainpeddoivn by a stirrup or fstrap 22 (see Fig. 2) tokeepl it from warping. The receptacles16 may vlie upon crossbraces 23;

In order to maintain, 'as far as possible, an even heat in each of the compartments 17., Ilarrange the .receptacles 15 and 16 as illustrated in Fig. 1. In Aother Words, all of the receptacles do not project into the rebox tothe same extent. As can be A.seen,the lowerV .receptacles Ldo not extend into the iireboX asfar .as the top receptacles; this :is because they are nearer the fire; on the grate 24 and do not need gas much of yan exposed surface .asthose farther from the lire. The amount of exposed surface of a receptacle 15 or 16 "is dependent uponits location relative tothe fire. -I1desire,.as far as possible, .to keep :the arcaniV thezexp'osed portion Yof each carried by the wheel-frame 42.

theV said receptacles to the action of the fire.

The front end oit each compartment 17 is provided with a hinged door 26 arranged to swing ,inwardly to permit of the introduction of wheeled trays 27 carried by a portable truck 28. The trays 27 support the articles to be baked, suoli as bread, cake or the like.

To prevent the heat in one compartment 17 from escaping into another, l provide seals 29, which are convened and contain a packing, such as mineral-wool or asbestos 30 (F ig. l). The seals are secured at each end thereof to the front wall 31 of the oven and are located so as toV contact with the doors Qwhen said doors are closed and to straddle the shelves or partitions 18, thereby completely sealing the joints.

To carry 0E theV vapors from the compartments when the doors are opened to re move any of the trays, l provide` a hood 32 which communicates with a iiue 33, which in turn communicates with the stack et when the damper 34 is opened or raised to open the passage 35 in the partition wall 36. rlhe damper 34 will be raised only when it becomes necessary to carry 0E the vapor from the compartments 17. Y

The compartments 17 are heated by steam `within the receptacles 15 and 16. As can be seen, the receptacles 15 and 16 are inclined toward ythe ireboX in order that the water 25 willremain at the heated end of said receptacles.

f ln combination with myy improved oven,`

Vthe traysroll. rhe trame-members 3S carry blocks 40 which slidably engage posts s1 Each post 41. has secured thereto a block 43, to which is pivotally connected one end of a togglemember eta, the other toggle-member 4,5 being connected, at one oiits ends, to the block 40. on the truck-frame members 3S, thefree ends of the said togglemembers being connected at 46. Linksli? are connected to said toggle-members at the points 46, the other end of said links being-.connected to arms 48 carried by a shaft e9. A leverA .50

mageos is employed to actuate said shaft to cause the toggle-members slet and ll5 to operate to raise or lower the end 51 of the truck 28.

@ne end of each rail 39 is provided with an opening 52 for the wheels 53 of the trays 28 to drop into iniorder that the trays will be locked against movement while the truck is being moved from place to place. TWhen the truckis to bemoved the toggles M and Ll5 will be operated to raise the end 51 of the truck. Fig. 1 illustrates the said end 51 of the truck lowered, the toggles being out of alinement. When the toggles are brought into alinenient the said end 51 of the truck will be in raised position and may be moved. lWhen a tray isrolled cti the truck, the wheels thereof will pass throughV slots 54 in theseals 29 onto rails 55 on the side-walls of the chamber 2 (see Fig.6).
